10.20.5 ThermocoupleType and CommunicationProtocolType ToC Previous Next

This two Variables are used to specify the type of connected external temperature sensor and the used communication protocol between the sensor and the control system of the TCD.

The TypeDefinition for both Variables is MultiStateValueDiscreteType, so the Properties EnumValues and ValueAsText must be filled with the supported values out of Table 11 and Table 12.

Table 11 – Values for ThermocoupleType

EnumValue ValueAsText Description
0 OTHER Other sensor type
1 E Type E sensor: NiCr-CuNi
2 J Type J, L sensor: Fe-CuNi
3 K Type K sensor: NiCr-Ni
4 N Type N sensor: NiCrSi-NiSi
5 T Type T sensor: Cu-CuNi
6 PT100 Pt 100-Sensor

Table 12 – Values for CommunicationProtocolType

EnumValue ValueAsText Description
0 OTHER Other connection type
1 LOCAL Communication integrated in the local control system (local input)
2 PROFIBUS Values via Profibus
3 OPC_UA Values via OPC UA
4 I2C Values via I2C
5 CAN Values via CAN

Which sensor types and protocols and combinations are supported is device dependent. Especially when the CommunicationProtocolType has the value 1 (LOCAL), the ThermocoupleType could be set to a fixed value by the TCD.
